Abstract

PURPOSE:To extend the recording time automatically by allowing an automatic answering recording device to send an answer signal for time extension to a talking side at every lapse of a prescribed time and to send a signal for time extension request to the opposite party when the extension is desired. CONSTITUTION:When an incoming call detection circuit 4 detects it that a telephone call or a FAX line is connected during absence via a speech circuit 3 and a hook switch 2, automatic answering recording is started. A voice control circuit 11 starts counting the elapsed time from the start of the automatic answering recording and sends a message representing whether or not the automatic answering recording is to be extended to the opposite party after lapse of a prescribed time. When a DTMF signal representing the extension from the opposite party comes, the count of the elapsed time is again started without termination of the automatic answering recording and the similar processing loop to above is repeated and when the signal requesting of extension from the opposite party is not received, the automatic answering recording is finished.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone or fax machine having an answering machine function.

[0002]

2. Description of the Related Art Conventionally, when recording the contents of a call in an answering machine, a cassette tape or a semiconductor memory is used as a recording medium, and the recording is started from the start point of a designated recording area of the recording medium. However, recording was ended at the end point of the specified recording area. In the conventional answering machine as described above, only the recording time corresponding to the size of the recording area can be recorded at one time, so that it is impossible to handle as long as possible. In particular, in a voice synthesizing voice mail system using a semiconductor memory as a recording medium, generally, the recording time in the recording area is short. Therefore, it was difficult to record all the contents of the call.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above point, and automatically determines whether the recording time should be extended or ended according to the request of the other party, and the request is made. It is to provide the thing which can perform the processing according to.

[0004]

In order to solve the above-mentioned problems, the present invention sends an answer signal of the above-mentioned time extension to the caller side every time the answering machine side has passed a certain time, and the caller side makes a call. Provide an answering machine that can automatically extend the recording time of the answering machine of the other party by sending an answer back signal requesting the time extension to the other party when it is desired to extend the time. There is a thing.

[0005]

With the above construction, the recording time can be automatically extended in the recorded message apparatus according to the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an answering machine according to the present invention will be described in detail below with reference to the drawings. The telephone in the embodiment of FIG. 1 includes a handset 1 for making a call, a hook switch 2 for closing and opening in conjunction with raising and lowering of the handset 1, and a call circuit 3 for performing signal conversion between the handset 1 and a line. An incoming call detection circuit 4 that outputs a signal that rings an incoming call signal to notify an incoming call, a selection signal generation circuit 5 that generates a selection signal for dialing, and a dial that inputs a dial number of a call destination. A key 6, a message key 7 used for recording, playing and erasing a message, a display device 8 indicating whether or not each message is recorded, an erase key 9 used for erasing a message, and a message storage The message memory 10 and the input from the call circuit 3 are converted into digital values by the ADM method and recorded in the message memory 10, or recorded in the message memory 10. A voice synthesis circuit 11 that converts the reproduced signal to an analog value and plays it back, and stores the region start position, region end position, playback start position, and playback end position of each message to control the voice synthesis circuit 11. According to the output of the control memory 12 and the message key 7 and the erase key 9 for reading and writing, the control memory 12 is read and written, and the voice synthesizing circuit 11 is controlled to perform recording, reproducing and erasing operations, and the display device 8 A control circuit 13 for controlling the signal, an amplifier circuit 14 for amplifying the reproduction signal output from the voice synthesis circuit 11, and a speaker 15 for outputting the reproduction signal and the incoming signal. Figure 2
Shows a difference in configuration between an answering machine according to the present invention and a conventional answering machine, and a portion surrounded by a broken line in 26 is a circuit added for the answering machine according to the present invention.
Is an amplifier circuit for amplifying an input signal, 21 is an ADM recording circuit, 22 is an ADM reproducing circuit, 23 is an amplifier circuit for amplifying an output signal, 24 is a recording data input / output circuit, and 25 is a message memory. An access circuit, 27 is a DTMF signal processing circuit, 28 is a microcomputer for performing central information processing,
Reference numeral 29 is a timing control circuit, and 30 is an external input / output circuit. FIG. 3 is a block diagram showing the flow of operation of the speech synthesis circuit 11 of FIG. 31 is the start of operation, 32
Is the start of recorded message, 33 is the elapsed time check, 34 is
Transmission of a message as to whether to extend or not, 35, response processing of DTMF signal by combination of two kinds of voice band frequencies, 36, judgment, 37, end of absence recording, 38,
This is the end of the operation, and 39 is the time extension process, S 1 and S.
2 shows a loop returning to the elapsed time check.

Next, the operation of the answering machine according to the present invention will be described with reference to FIG.
The flowchart will be described. At 32, when there is no telephone or fax line connected, absence recording is started. The counting of the elapsed time starts from the start of the above recorded message, and at a time point 32 when a certain time has elapsed, a message 34 as to whether to extend the recorded message is automatically sent to the other party. At 36, when there is a DTMF signal indicating extension from the other party, the recording of the elapsed time is started again without ending the recorded message. Thereafter, the same loop as above is repeated until the signal requesting extension of the other party does not come. D requesting extension of the other party of the call
When the TMF signal does not come, the recorded message is ended.

[0008]

As described above, according to the answering machine according to the present invention, the length of the recording time can be extended as needed, and all the contents of the message can be transmitted in one call. It is possible to eliminate discontinuity during playback.
